Planning a central heating installation in Caversham but worried about the costs involved? You’re not alone – understanding heating system prices can be confusing, with quotes varying significantly between installers. At TS Gas, we believe in complete transparency when it comes to pricing, so we’ve broken down exactly what you can expect to pay for a new central heating system in 2025.
The Main Components and Their Costs
Boiler Costs (£1,200 – £3,500) The boiler represents the largest single expense in any central heating installation. Combi boilers typically cost between £1,200-£2,800, whilst system boilers range from £1,400-£3,500. The final price depends on the brand, output rating, and efficiency level. Premium brands like Worcester Bosch command higher prices but offer superior warranties and reliability.
Radiators (£80 – £300 each) Modern radiators cost between £80-£300 depending on size and style. A typical three-bedroom home requires 8-10 radiators, so budget £800-£2,000 for the full set. Designer radiators can cost significantly more, but standard panel radiators offer excellent performance at reasonable prices.
Pipework and Fittings (£500 – £1,200) This includes all copper piping, joints, valves, and fittings needed to connect your system. Costs vary depending on your home’s layout and whether existing pipework can be reused. Two-storey homes typically require more extensive pipework than bungalows.
Heating Controls (£200 – £800) Basic programmer and room thermostat combinations start around £200, whilst smart heating controls like Nest or Hive cost £300-£800. Smart controls offer superior energy savings that often justify the extra investment.
Labour Costs: What You’re Really Paying For
Labour typically accounts for 40-50% of your total installation cost. In 2025, expect to pay:
- Gas Safe registered engineer: £350-£450 per day
- Heating system fitter: £250-£350 per day
- Additional trades (electrician/plumber): £200-£300 per day
A complete central heating installation typically takes 3-5 days depending on your home’s size and complexity. This includes boiler installation, radiator fitting, pipework, and system commissioning.

Additional Costs to Consider
System Flushing (£300 – £500) Essential for removing debris from old pipework, this process ensures your new system operates efficiently from day one.
Magnetic Filters (£150 – £250) These devices protect your boiler from heating system debris, extending its lifespan and maintaining efficiency.
Thermostatic Radiator Valves (£25 – £50 each) TRVs allow individual room temperature control, improving comfort and reducing energy consumption.
Building Regulations Compliance (£150 – £300) All new heating installations must comply with Building Regulations, requiring proper certification and sometimes Building Control notification.
Ways to Reduce Installation Costs
Timing Your Installation Summer installations often cost 10-15% less than winter emergency replacements. Boiler manufacturers also run seasonal promotions that can reduce equipment costs. For more detailed pricing information, our comprehensive guide on boiler installation costs in 2025 breaks down all the factors that influence final prices.
Keeping Existing Pipework If your current pipework is in good condition, reusing it can save £500-£1,000 on installation costs.
Choosing Standard Components Opting for standard white radiators and basic controls instead of designer alternatives can significantly reduce costs without compromising performance.
Government Grants and Financing
The Energy Company Obligation (ECO4) scheme provides grants for qualifying households, potentially covering the full installation cost. Additionally, many suppliers offer 0% finance options, spreading costs over 5-10 years. Our detailed guide on new boiler finance options explains all available financing methods to help make your installation more affordable.
Why Professional Installation Matters
Whilst DIY installation might seem tempting, central heating work requires Gas Safe registration and extensive technical knowledge. Poor installation can void warranties, create safety hazards, and result in inefficient operation that costs more long-term than professional installation.
